OSLUNID, or WORCESTER, MASSACHUSETTS, ASSIGNOR TO, THE LIQUID CARBONIG CORPORATION, OF CHICAGQVI ILLINOIS, A CORPORATION OF DELAWARE LABEL-DATING DEVICE I Application filed May 11,

This invention relates to a devicefor dating labels placed on cans, bottles or the like and the principal objects thereof are to provide means for applying the date or a code nume her on the back of the label, where it is not to be gummed preferably, and where it will not be seen by anyone unless the label is taken off the articleor the gum softenedup' onthe back; also to provide means, timed with the operation of the picker fingers, whereby the date is stamped on the back of the label, preferably as it is in the holder and at the time when the picker fingers moveover the table to aflix the previous label to the container; to provide means for swingingthe datlng stamp into position to register with the inking pad and for swinging it into position. to"

register with the labels in the holder; to provide means for moving the stamp longitudinally against the pad and against the holder; to provide means for turning the pad so that the ink will be distributed on it. uniformly and to provide means whereby the printingor 1 dating device will be heldagainst vibration or chattering while it is applying the date to the label. Other objects and advantages oftheinvention will appear hereinafter.

It is also desirable that a mark shall be placed in a position'where it doesnot' disclose any information tothe consumer or to the dealer but can be made plain to the manu-, facturer whenever desired. r v This is accomplished according to the present invention by means whichdoes notadd anything to the cost of labeling or delay it in any way. 'Forthe purpose of accomplishing the objects mentioned above the. labeling machine 10, which may be of any type, is shown as provided with a paste pot 11, gumming cylinder 12, pickers 13, label holder 14 and gumming roll 15. 7 These partsmay be mounted and connected witheach other in any of the usual ways. I have illustrated herein one of thecommon ones. V r

This machine is provided with a main shaft 16 having connections (not shown) for operating-the gumming cylinder, gumlrolls and pickers. On this shaft are two cams 17 and 18. -The double cam 17 operates .a lever 19' which, by means of a rod 20 which canbe shortened and lengthenedby a turn buckle 21,actuates a bell crank 22. This bell crank, by means of a yoke or grooved collar 23, slides a shaft 24 in its bearings 25and 26-. The two extreme positions of this shaft are indicated in full and dotted lines in Fig. 1. It will be seen that for each rotation'of the shaft 16 this shaft is moved out and in twice.

The single cam 18 actuates a'lever 28 which, by means-of an adjustable rod 29, swings an arm 30 in which the shaft 24 is keyed. Therefore, it will oscilllate this shaft irrespective of'its longitudinal position The result is that this shaft can swing so that an offset arm 31 constituting theend of the shaft will move from the full line to the On the shaft 24, as has been stated, is fixed the collar 23 and this is provided'with a steadying bifurcatedarm 32. This collar being fixed onfthe shaft, this steadying arm will swing back and forth to the two positions shownin Fig. 5. On the bearing 26 is fixed projection 33 which has a longitudinal bar 34 adapted t-o be'surrounded'by the slot on the arm 32 at. a certain time for the purpose of s'teadying the arm 31.

dotted line position ation. V The dating stamp simply constitutes a holder. In

I Fixed on the bearing is an upright piece having a horizontal sleeve 36 adjustably fixed thereto. This sleeve extends upwardly and carries an ink cup 37 which neednot be described in detail as it is made like an ordinary oil cup designed to drip the ink from a nozzle 38 down on'an-inking member 39. This inking?j-member is-provided with a V-shapedgrooveA-O for receiving the ink. This groove is providedwith prfor ations 41 through which the ink oozes into a recess in which is an ink pad 42 for taking up the ink. This ink pad will then be con:

stantly an d rod'43which slides in the'sleeve 3B. A spring 44 between the end of this'sle'eve and the back of the ink device 39 normally forces the pad outwardly. On the sleeve 36 is fixed a spring 45 which is-arranged'in an angular position andengagesthe'rear surface of the inking member 39 so that whenever this ink pad is'forced back the spring will'have to yield andwill turn this inking member 39 ashort distance like a ratchet. Thusat each operation the ink pad is located in a different position and the ink dripping from' the inking device 37 will be evenly distributed and also a different part of the pad will be presented to thedating stamp with each operholder 46 mounted on the arm 31and provided with one or more screws 47 by which type orthe like48 may-be clampedin'the this way thetype can bechanged every day if i "and it will be understood that the date can be in code if desired.

and then sweeps across apair of pickers 13.

The operation of he machine will be understood from what has been stated. As the shaftlfi rotates, the gumming roll 15 moves down and engages the gumming cylinder 12 the front surfaces of come up and engagethe front label in the holder to apply two strips of paste along or and take it, out of the holder near the two opposite edges of. the front label and to the vertical position shown in Fig.1 where the label is applied to the bottle or other container. These features 'are'well known in labeling machinesf As the shaft 16 rotates through a complete revolution the lever 19 is. operatedtwiceto reciprocate .the shaft 24"and therefore the dating stamp twice. Also once during each revolution of theshaft 16 the lever 28 is actuated to swing the'dating stamp out and a positionto encounter the bottle.

in. .-Therefore the operations occur as follows: The pickers take the label out into The bell crank 22 moves the dating stamp inwardly against the front label in the holder to date theback thereof. I Then the shaft 24 moves uniformly inkedbythi's means}' Theink pad is supported on a horizontal Qthe'dating stamp desired togive a different date A Now the pickers 13 7,

outwardly to the dotted line position in Fig. I

1. Just then the cam 18 swings the dating stampback to the full line position in Fig. 3 in registration with theinking pad. The pickers again come up and take off to 'attach it to the container.* Now the cam 17 moves the shaft 2& back to the full line position in Fig; 1 and then out again to the dotted line position. Thus ink is applied to the dating stamp. .Thisoperation moves the inking pad back against the spring 45 and then moves it forward again to release it which causes the inking pad to turn a'step.

As the shaft 24 moves back to the leftwhen the label v g V is to apply the date of the label, the bifurcated arm 32 comes into regis-' tr'ation with the projection 34 andprevents any, vibration of the shaft 31 at the time of printing. 7 the inking of the type as it 1 l5 l'lOt/ SO essential'at that time. I V

This action does not occur during It will be observed that now the stampis inked f'again and operations above specified. The label is dated area, the'printing or dating mechanism is held against chattering or vibration during the dating: operatiomthe' inking pad is turned at each operation so evenly and yet no period required for labeling and thereis no as to distribute the .ink time is taken'from the cost addedij'to'the operation of the "machine.

The date on the label cannot be seen unless the -label'is- 'taken ofi the container'or loosened at one side and turned back.
